The present invention provides the following process for produci ng and the like, which enables the production of an ether compound, which is useful for chemical amplification type resist compositions, synthetic intermediates of pharmaceuticals, paints, or the like, with less side reaction and in high yield.
A process for producing an ether compound having a group represented by the general formula (II)
wherein R1, R2 and R3 may be the same or different, and represent substituted or unsubstituted alkyl, substituted or unsubstituted aryl or substituted or unsubstituted aralkyl, or R1 and R2 form cycloalkyl together with an adjacent carbon atom,
which comprises allowing a compound having a hydroxyl group (including a carboxyl group) to react with an alkenyl ether represented by the general formula (I)
wherein R1, R2 and R3 have the same significances as defined above, respectively.
本发明提供了以下用于生产等的过程,该过程能够生产醚化合物,该化合物对于化学放大型抗蚀组合物、药物合成中间体、涂料等具有用途,且副反应较少且产率高。一种生产具有由通式(II)表示的基团的醚化合物的方法,其中R1、R2和R3可以相同也可以不同,并表示取代或未取代的烷基、取代或未取代的芳基或取代或未取代的芳基烷基,或者R1和R2与相邻碳原子一起形成环烷基,包括允许具有羟基(包括羧基)的化合物与由通式(I)表示的烯基醚发生反应,其中R1、R2和R3分别具有上述定义的相同含义。
